Avoid and report Mozilla tech support scams

Mozilla does not charge for downloads, upgrades or technical support, and does not endorse any company that does. Companies that ask for payment or personal information for installing, updating or providing support for Firefox or Thunderbird are not affiliated with Mozilla and should be avoided.

Protect yourself from scams

Visit the official Mozilla Support site (https://support.mozilla.org) or other recognized resources for all technical support issues. There are no other Mozilla-endorsed technical support companies, and any other company that's using the Mozilla name or logos to claim affiliation with Mozilla should be reported here.

Mozilla does not offer telephone support. Do not call or give information to agents claiming to represent Mozilla.
